Also changes the schemas a bit (still don't care about migrations),
switches to named_params!, fixes up perf issues when ingesting manifests
and/or hrefs into sqlite, etc. Adds sample queries such as "CudaArtifact
conflicts" to datasette config, which explain some issues associated
with choosing an evalModules schema on the cudaPackages side.
This way we don't error-out when a path is a directory. That said, we're
still only including the root in sidx.db (e.g. manifests/ but not
manifests/*.json). We should change that next.
Also renamed "blob_id" to "blake3_id" because datasette has a special
branch for ${column}_id referencing a table that contains ${column}
First attempt at both Rust and snix-castore.
I'll start by putting together a single-file CLI app,
no splitting modules out until needed, no separation of concerns.
Currently, just the fetching is implemented:
```
$ sidx pkgs/dev*/cuda-*/cuda/manifests/*.json
```
npins: init
